The techniques and capability to regenerate asexual embryos from walnut cotyledon tissue have been developed. Tissues from five Jug1ans regia cu1tivars, Jug1ans hindsii, and pterocarya sp. have been used. More than 100 asexual embryos have been selected from among the thousands produced. The sequence of procedures needed to obtain plants from these embryos have been worked out, and more than a ...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed for a monotypic species endemic to subtropical China, Cyclocarya paliurus, to help infer the evolutionary histories of ancient monotypic genera in subtropical China. • METHODS AND RESULTS Using the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) protocol, 28 primer sets were identified in two wild population...

Abstract To investigate the decay extent of wooden components in ancient buildings Danxia Temple, absorption peak intensities, changes chemical components, and cellulose crystallinity red oak (Quercus sp.), birch (Betula maple (Pterocarya sp.) were determined analyzed using Fourier-transform infrared spectroscopy. The results are as follows: (1) intensities representing hemicellulose decreased ...
